The International Betting Integrity Association (IBIA)’s 2025 Sports Betting Integrity Report shows 300 suspicious betting alerts during 2025.
The International Betting Integrity Association‘s (IBIA) 2025 Sports Betting Integrity Report shows 300 suspicious betting alerts were reported last year, the highest annual total to date.
The figure marks a sharp increase from 232 alerts recorded in 2024. It also continues a rising trend seen since 2021, when 236 alerts were logged.
According to the report, football generated the largest share of alerts, with 110 cases reported during the year. Tennis followed with 74 alerts across multiple competitions.
Table tennis and esports each produced 34 alerts, while basketball accounted for 27 alerts.
The remaining cases were spread across cricket, baseball, handball, boxing, MMA, snooker, volleyball, and horse racing. In total, alerts involved 16 different sports.
Europe remained the most affected region, representing 35% of all reported alerts; North America followed at 16%. South America accounted for 15%, while Asia contributed 13% and Africa represented 10% of alerts.
A further 11% were classified as global. These global alerts were largely linked to esports events without fixed locations.
Country-level data showed football alerts concentrated in Brazil, Bulgaria, Romania, and Albania. Tennis alerts were distributed across Europe, Asia, and Africa.
Table tennis alerts were concentrated in central Europe and the US, while esports alerts were not assigned to specific countries due to the transnational structure of competitions.
The report also outlined enforcement outcomes connected to IBIA alerts. During 2025, 54 matches were confirmed as corrupted using IBIA data.
These cases led to sanctions across several sports. Tennis accounted for sanctions against 10 players and six umpires.
Football and tennis produce the most issues
Football sanctions involved two players and one club. Esports cases resulted in one player and one team being sanctioned. Additional sanctions affected two darts players and one MMA athlete.
All sanctions were announced during 2025 following completed investigations.
A five-year analysis showed football and tennis consistently produced the most alerts. Football had an average of over 90 alerts between 2021 and 2025, while tennis had more than 70 alerts on average per year.
The statistics revealed a tendency towards betting markets with high liquidity.
Football ranks highest in terms of betting volume, and is also the most popular sport globally, increasing the chances of suspicious betting activity.
Tennis ranks below American football, basketball, and horse racing in terms of betting volume. However, previous studies have shown that match-fixing is a systemic problem at the sport’s lower levels, which typically avoid attracting significant attention.
In Africa, between 2021 and 2025, the IBIA reported 117 alerts regarding sports events on the continent. The sports events were dominated by football and tennis, coinciding with the rise of betting in the region.
The revenue generated from online betting in Africa is set to increase rapidly between 2025 and 2030.
According to the report, GGR in the region sat at just $3bn in 2021, but is expected to grow to $8.4bn in 2025 and $16.4bn in 2030.
